| Abstract: |
| In order to study the characteristics of bi-stable piezoelectric energy harvesting system,this paper is primarily focused on constructing the equivalent mathematical model of bi-stable piezoelectric cantilever energy harvesting systems under external excitation.Secondly,adopting the harmonic balance method,the equations of dynamic response were derived.The dynamic response curves show the jump phenomenon and the unstable region of multiple solutions.Finally,the effects of different parameters on the dynamic response of the system were analyzed and compared.The numerical results provide a theoretical basis for the optimal design and application of bi-stable piezoelectric cantilever energy harvesting system. |
